SPECIFICATION forming part of Letters Patent No: 244,878, dated July 26,1881.

' Application filed May 31,1881. (No model.)

To all whom/wit may concern:

Be it known that I, LAWRENCE FORKNER, Jr., of Sweet Water, in the countyof Monroe and State of Tennessee, have invented a new and usefulImprovement in Railroad-Crossing Gates, of which the following is afull, clear,- and exact description, reference being had to theaccompanying drawings, forming part of this specification.

My invention relates to cattle-gates for railroad-crossings, which areautomatically operated bymeans of afalse track which is adapted to sinkunder the weight of the cars and oscillate a pair of levers, .to whichthe gates are attached by means of chains and pulleys.

My invention consists in certain peculiarities of construction andarrangement, as hereinafterdescribed.

In the drawings, Figure 1 represents a top view of the gates with thetrack broken away; Fig. 2, a side elevation of the gates, and aseetional view of the track through line 00 w of Fig. 3; and Fig, 3,aview showing the practical method of operating the gates.

A is a platform constituting a section of the track proper, within andabove which is supported a false track,B. This track is so arranged thatits two rails will lie just within the two rails of the said platform,and it is supported upon levers a, which are pivoted in slots on theunder side of the false track and rigidly secured to a transverse shaft,1), which is journaled in the under side of the said platform. A shaft,b, with such levers is located at each end of the platform, and on eachside of the platform the projecting ends of the said shafts are providedwith upright arms 0 for operating the gates D. The said gates aresupported at the sides of the platform in slotted frames E, which areprovided with friction-rollers at the top and bottom, between which thegates are made to slide back and forth by means of two levers, d,pivoted at their lower ends to the bottom of the frames,

outside of the frames, to pulleys ll, secured to the sides of the framesat their inner or forward ends, and thence in a rectangular direction tothe tops of the said arms 0, to which they are secured. t

Rubber cushions m m are arranged on the inner surface of the frames E,at their rear ends, to prevent jarring when the gates are thrown back.It is also designed that suitable springs shall be attached to levers ain such manner as to force the false track up to 'its normal positionafter a train of cars has passed over, and that weights of wood or metalshall be suspended from the cords to hold them taut when slackened bythe oscillation of the arms.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-'- In a gate for railroad-crossings, thecombination of the false track B, horizontal shafts b, havingsupporting-levers a and oscillating arms 0, the gates D, levers d, andsprings e for holding the gates closed, supporting-frames E, havingcushions an, inner pulleys, l, and outer pulleys, h, and cords g,connected with the vsaid oscillating arms, substantially as shown anddescribed.
